FINISHING WELT.

l Application ledFebruar'y 2, 1925. Serial No. 6,363.

To all whom t may :concern:

Be it known that I, ROBERT C. SGHEMMEL, a'citizen of the United States, residing at Union City, in the county of Randolph and Stateof Indiana, have invented certain new and useful Improvements in Finishing IVelts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others i0 skilled in the art to which it appertains .to

make and use the same. f

My present invention relates to improvements in finishing welts such as used in trimming automobile bodies, tops, or interiors when required, other vehicles, furniture, etc., and contemplates more particularl stated, what -is known to the trade as a lind-nail welt, wherein the attaching means is hidden by the Welt itself when aplied 'in operative position, as exemplified y U. S. Letters Patent No. 1,226,600, issued to me under date of May 15, 1917.

In the manufacture of welts of the character indicated, it is a mattei' of prime importance that they possess great flexibility to facilitate comparatively short turns, eitherA in a horizontal or vertical direction, as ther welt is applied to the more or less curved surfaces of the body or article in process of trimming.

It is therefore an object of this invention to produce in running lengths or'yardage, a finishing welt which in itself serves to conceal the tacks or other fastening means, by which it is secured in place, and at thesame time an article that is remarkably flexible to assist in turning corners without liability of puckering A further object is the speedy, accurate and economical production of welts of the character indicated, employing an elastic body or core Which assists in retaining the finished article in its normal applied .position, by agency of the inherent elasticity of the core itself.y

- With the foregoing and other objects in view my present invention-will `now be par 4ticularly described', and hereinafterpointed out by the appended claims.'v

In the accompanying drawings" which form partv of this application for Letters Patent, and whereon corresponding reference characters indicate likeparts in the several views: Y

. Figure 1 is a perspective view, in section at one end, of a fragment of Welt embodying the presentimprovements; A

Figure 2 is a relative enlarged cross sectional view of the improved blind-nail welt in process of application to an article of manufacture, such for example, as the back of an automobile seat; and

Figure-3 is also a cross sectional view, corresponding With Figure 2, but showing the welt in its finished, applied position, and the fastening tack concealed thereby.

Reference being had to the drawings and numerals thereon, 1 indicates an elastic flexible core, preferably of rubber molded to the desired or required cross sectional shape, and 2 is a beading-cord of any suitable flexible material, but preferably of tightly twisted paper for economy of production. These two parallel members 1 and 2 are enclosed or encased ina wrapper of suitable flexible material, preferably a unitary stri of leather, imitation leather, or

fabric o any kind, either with or without a nap of mohair or plush according to requirements of the individual job to be trimmed. 1

This wrapper or envelope starting at 3 encloses the core 1 to form a Welt body 4 as clearly shown by the drawings, doubles up`- on itself as at 5, thus forming a two-ply Welt-base 6, thencef'encircles the cord 2 to form a bead 7, and terminates at 8 adjacent the starting point 3.

During the process of formation as aforesaid the elastic core 1 is stitched vthroughout.

its entire length, as at 9 to and through the two underlying thicknesses of its wrapper, as shown, and in like manner that portion of said wrapper which encloses the aforesaid cord 2, is also stitched permanently together as at 10 to complete the bead 7, as best shown by Figures 2 and 3 of the drawings.

This improved form of welt having been made substantially as shown and described, is applied by agency of at headed tacks such as 11, driven at intervals through the two-ply welt-base as indicated by Figure 2i.,Y

While the welt-base 6 being drawn d'own to its final position as shown by Fi ure 3, the trimmer holds the welt-body 4 1n substantially the position indicated by Fig ure'2 under-'slight tension at its lower edge,

so that when released the said body automatically and positively snaps down to the normal applied position o f Figure 3 because of the inherent elasticit of the core 1 itself, and while the present i lustrations show the stitches 9 passing through the welt body l, and through but one p-ly of the two-ply base 6, it is obvious that said stitches may, if de- K sired, extend entirely through both of said base plies as the means of connecting said Awelt-body-tlo the tack-receiving base, with; out in the least departing from the spirit of ythis invention as set forth in the following claims.

This being the form and general construction of my present improved finishing welt, its use and operation will be uite apparent from the foregoing, and furt er'statement as to its Well known uses is considered unnecessary. l

Having thus described my invention what I now claim and desire to secure by Letters Patent is:

l. A nishing welt of the blind-nail type including in combination a: tack-receiving base, and an independent tack-concealing welt body permanently secured to said base by fastening means passing through said body and spaced inwardly from the edgel thereof, said fastening means connecting said welt-body to the base.

2. A finishing welt of the blind-nail type including in combination a tack-receiving base, and an independent tack-concealing welt-body permanently secured to an hinged passing t rough said body and spaced inwardly from the edge thereof, said fastening means connecting said welt-body to the base.

upon said base by fastening meansv ly secured to sald base by fastening means passing through said body and spaced inwardly from the edge thereof, said fastening means connecting said welt-body to the base.

4. A finishing welt of the blind-nail type, including in combination a tack-receiving base, and an independent tack-concealing Welt-body having an lelastic core hinged to said base by means of stitches passing through said elastic core and spaced inward- 1yl from the edge thereof, said stitches connecting said Welt-body to the' base.

5. A finishing welt of the blind-nail type including in combination a tack-receiv? ing base, an .independent tack-concealing welt-body permanently secured to said basc by a line of stitches passing through said body and spaced inwardly from the edge thereof connecting said Welt-body to the base, and a relatively fixed surface bead parallel with the welt-body aforesaid.

6.l A nishingwelt of the blind-nail type includingin combination a suitable base, an Vindependent elastic Welt-body permanently .inged to said base bv means of stitches passing through said body and spaced inwardly from the edge thereof connecting said weltbody to the base, whereby the welt-body automatically closes ov ar the base aforesaid by reason of its inherent elasticity.

In testimony whereof I afix my signature.
